As NBC News's Brad Jaffy noted, Trump's strangely specific denial that he watches TV came immediately after an MSNBC guest, Washington Post reporter Philip Rucker, said that Trump had been watching a lot of cable news coverage of the unfolding conspiracy scandal engulfing his son and son-in-law.

So?

It's bad if a president is this thin-skinned or impulsive.

While Trump's TV habits are hardly the most problematic thing about his presidency, this is still an obvious lie, and it's bad when presidents lie.
